Ive got a couple hacked up studs on my JDM uppipe that I want to replace, but Im not having any luck with the traditional double nut method (no thread left) anyone have any experience with trying to get these bastards out?

P.S. Expensive stud replacements via dealerships, vendors, etc. are not an option I have all the tools, just dont know what direction to take right now.

double nut method is the easiest if you haven't totally jacked the threads. If not a good pipe wrench (small to medium size) usually can hack the job but is much more a pain. I'm hoping becuse your car isn't that old the bolts will slip out. Use some good break free lub on the base too

I suppose if its worse to worse you can always drill them out rethread and get new studs

Its an ancient uppipe... like from a early 90's WRX. They dont want to move. And I dont want to destroy this uppipe either, its rather nice

Did you try heating the area around the stud with mapp gas? Liquid wrench?
Sometimes, in similar cases, I have actually done these things:

1. heat
2. liquid wrench penetrating oil
3. try actually "tightening" the stud further into the flange, just a hair then try backing it out. Believe it or not, this has worked.
4. Try tapping on the stud "sideways" (perpendicular to the axis of the stud) with a small drift and a small hammer. Mount the pipe up in a good vise and tap the studs repeatedly and try the above steps after.

I've never messed with a Subaru up-pipe, but I've palyed with plenty of exhaust studs in the VW world and they can be the worst.

Sounds good, ill bust out the liquid wrench and some heat tommorow (I dont expect anythign new, but ill try)

if all else fails bring it to a mechanics shop. my friend had a broken stud in his greddy turbo kit, and they got it out easily. and for 40 bucks too.

Soak in liquid wrench over nite and then get the easy outs out and drill the whole in the middle and take that sucker out!!!

Liquid Wrench is a must for all turbo owners!!

drill through it, from one side to the other, stick a dispoable alan wrench in there and twist whil having it attached to a vice grip
